Wash 500 g potatoes with the skins on and boil them in enough water to cover. Drain them when a chopstick or skewer enters without firm resistance. Peel and mash the potatoes while they are still hot, stopping while small pieces remain instead of working them into a completely smooth paste. Finely chop 100 g cucumber, 70 g carrot, and 60 g onion. Distribute 0.5 tsp salt over the vegetables and let them stand for 5 minutes, then squeeze them by hand or in a clean cloth until they no longer drip. Drain 150 g canned tuna in a strainer until excess oil stops falling. Add the vegetables and tuna to the mashed potatoes and fold lightly to separate the tuna. Add 5 tbsp mayonnaise and 1 tbsp whole grain mustard, then continue folding from the bottom with a spatula. Avoid repeated pressing, which would mash the remaining potato pieces. Refrigerate the finished salad for 20 minutes and serve it cold. Thoroughly removing the vegetable liquid and tuna oil is what allows the measured mayonnaise to coat the mixture without a loose layer collecting in the bowl.

Instructions

Read the steps as a cooking flow: prep, heat, seasoning, doneness control, and finish.

6 steps
  1. 1
    Control

    Wash 500 g potatoes with the skins on and place them in a pot with enough water to cover.

    Boil over medium heat until a chopstick or skewer slides through easily, then drain before they cool.

  2. 2
    Season

    Peel the potatoes while they are still hot and mash them in a large bowl.

    Stop before they become completely smooth, leaving small chunks so the salad stays creamy without turning sticky.

  3. 3
    Season

    Finely chop 100 g cucumber, 70 g carrot, and 60 g onion.

    Sprinkle the 1/2 teaspoon salt evenly over the vegetables, toss lightly, and let them stand for 5 minutes to draw out moisture.

  4. 4
    Season

    Squeeze the salted vegetables firmly by hand or in a clean cloth until they no longer drip.

    Put 150 g canned tuna in a strainer and drain until excess oil stops falling.

  5. 5
    Prep

    Add the squeezed vegetables and drained tuna to the mashed potatoes, breaking up the tuna lightly as you fold.

    Add 5 tablespoons mayonnaise and 1 tablespoon whole grain mustard on top before mixing fully.

  6. 6
    Finish

    Fold from the bottom upward with a spatula so the remaining potato pieces are not overworked.

    Chill the salad for 20 minutes and serve it cold.
